Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional organ models use solvents (water or ethylene glycol) to accommodate energy devices, then the models can accommodate energy devices, but the models require refrigerated storage and antiseptic measures, leading to difficulty in long-term storage and solvent evaporation causing shape changes
Solution Approach 1:
The patent changes the fundamental parameter of the resin composition by incorporating specific electroconductive components (conductive filler, plasticizer, curing agent) in controlled amounts. This transforms the material from a solvent-based system requiring refrigeration to a stable composition that maintains its properties at room temperature, eliminating the need for refrigerated storage while preserving energy device accommodation capability
Solution Approach 2:
The patent creates a composite material system combining silicone resin base with electroconductive fillers (such as carbon black, metal particles), plasticizers, and curing agents. This composite structure provides both the electroconductivity needed for energy device accommodation and the structural stability for long-term storage without refrigeration, resolving the contradiction between adaptability and reliability
2Ease of operation
If conventional organ models use solvents to maintain flexibility, then the models are flexible, but the solvents evaporate over time causing shape changes and bleeding
Solution Approach 1:
The patent replaces the unstable, evaporating solvent components with a stable cured resin system that maintains its physical properties indefinitely. The curing agent transforms the plastic state into a cross-linked network structure that locks in the desired shape and flexibility characteristics, preventing both evaporation and bleeding while maintaining operational flexibility
Solution Approach 2:
The patent controls the amount of plasticizer within specific ranges (1-50 parts by mass per 100 parts of silicone resin) to achieve optimal balance between flexibility and shape stability. The curing process further modifies the physical parameters, transforming the material from a soft, evaporating state to a stable, cross-linked structure that maintains flexibility without solvent loss
